GASOLENE soLDERING-TooL.

Specification of Letters Patent.

Patented Dec. 3, 1907.

To all whom it may concern:

Be it known that we, WILLIAM E. CRANE and CHARLES D. PRATT, citizens of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful Improvement in a Gasolene Soldering-Tool, of which the following is a specification.

This invention relates to soldering irons and more particularly to gasolene heated soldering irons, the object being to provide a soldering iron so constructed that the flow of gasolene will be regulated so that a uniform blast is obtained at all times.

Another object of my invention is to provide the gasolene reservoir with a pump so that air can be mixed with the gasolene so as to give a strong blast when using as a torch.

With these objects in view, the invention consists in the novel features of construction,

inafter fully described and pointe out in the claims.

In the drawing forming a part of this specification:Figure 1 is a perspective view of our improved soldering iron showing apart of the reservoir covered with non-conducting material. Fig. 2 is an enlarged longitudinal sectional view of the same. Fig. 3 is a section taken on lines 33 of Fig. 2. Fig.4 is a section taken on lines 44 of Fig. 2. Fig. 5 is a detail top plan view of a portion of the same partly in section. Fig. 6 is a longitudinal sectional view of a portion of the oil chamber showing the pump in section. Fig. 7 is a detail sectional view of the pump valve.

Referring to the drawing A indicates a generator head formed of a flanged cap provided with oppositely disposed feet A, so as to hold the same in a vertical position, the flange of the cap being internally screw-threaded. The ca is provided with a vertical enlargement A provided with an oil cup A projecting out from its top having an outwardly projecting hook A, so that it can be hung up when desired. A central bore A is formed in the enlargement, reduced and threaded at its upper end and communicating with a threaded opening A, at its bottom, extending through the cap in which the threaded end B, of a tube B is secured. A threaded opening A is formed in the cap over the opening A", in which is secured the threaded end 0, of a bar 0 which is provided with a bifurcated end C and a reduced portion O Pivoted in the bifurcated end 0 of the rod O is the reduced end D, of a weight D pro-- vided with a groove D so that it can swing over the tube B. An armD projects out from the weight D on which the bifurcated end E, of a valve-stem E is pivoted, the bifurcated end of the stem is adapted to work over the reduced portion C of the bar C, so as to hold said valve stem in a vertical position. The stem E is provided with a polnted end E adapted to be seated in a tapering opening B forming a valve-seat, in the tube B.

Secured in the threaded flange 0f the top of the generator head A is the threaded end of a tube F, which is provided with an oppositely threaded end on which is secured a threaded flanged cap G provided with a threaded opening having an outwardly proj ecting flange G, in which the threaded portion of the cylinder H is secured by a nut I, carrying a rubber washer 1, adapted to engage the flange G, of the cap G. A cap J, is secured on the end of the threaded portion of the cylinder H, provided with a piston head K. The end of the cylinder H, is provided with a nozzle H, and outwardly projecting spaced rods L, provided with nuts L, and surrounded by coil-springs L arranged between cross bars L L, slidably mounted thereon. The cross bar L has a rod extending through an opening in the bar L and is provided with a pocket in which is secured a rubber packing L adapted to engage the nozzle H, and close the same so that air can be pumped into the gasolene reservoir formed by the tube and caps.

Securedin the reduced threaded end of the bore A is the threaded end of the pipe M, which carries a perforated shell N, forming a mixing chamber controlled by a needle valve 0. Secured to the end of the shell N is a perforated shell P, forming a combustion chamber which is provided with a square opening in its end in which soldering irons Q, are adapted to be secured by set screws P, so that the point can be readily removed and the iron used for a torch when desired.

The 0 eration is as follows :-The oil reservoir is led with gasolene and' the pump is operated a few times, then the needle valve is opened and the oil cup is filled with gaso lene and the valve is then cut off and the gasolene ignited heating the -miXing and combustion chamber. The needle valve is then turned on and a perfect blue flame will be obtained in the combustion chamber.

It will be readily seen that the gasolene will be fed through the end of the tube when held in a horizontal position and through the opening in the tube when tilted downwardly as the weight will open the valve and allow the gasolene to flow therethrough, thereby causing an even flow of gasolene and obtaining a uniform blast.

A covering R of non-conducting material is placed on the tube F so that the reservoir will be protected from the cold in winter and the heat in summer, and at the same time forming a handle for the tube. I

Having thus fully described our invention what we claim as newvand desire to secure by Letters Patent is 1. Ina gasolene soldering iron, the combination with a reservoir provided with a tube :having an opening formed adjacent one end, of a mixing and combustion chamber communicating with one end of said tube, a weight pivoted in said reservoirover said tube provided with an arm, and a valve stem carried by said arm, for the purpose described.

2. In a gasolene soldering iron, the coma tube extending within said reservoir communicating with said bore and provided with an opening adjacent its fixed end, a mixing and combustion chamber connected to said bore and controlled by a needle valve, an oil cup formed on the enlargement of said cap directly under said. mixing and combustion chamber forming an auxiliary heater, said oil cup having a downwardly curved hook projecting therefrom a bar secured to the forward cap of the reservoir and having a bifurcated end, a weight pivoted within said reservoir to the bifurcated end of said bar, directly over said tube, and a valve stem having a bifurcated upper end pivoted to an arm of said weight directly over said tube, substantially as described.
